Does anyone have the scenario where they have deployed Lync 2013 client to all workstations in their environment, but not all users are set up on the Lync server? By default, you will notice the Lync client starts up for every user who logs in. This is a problem for the non-Lync users because they get a sign-in screen they have to close on every logon. I'm looking for some ideas on how to turn off the automatic startup for non-Lync users only. Thanks.
